Project Structures - Login Form in PHP

We have index.php, config.php at a root of the directory. There are two folder css and js which contain main.css, main.js and our jQuery files.

  • index.php – going to be our main PHP file to display a login form
  • config.php – going to be our database configuration file where we’ll add all database details like server, database name, database username and database password.
  • main.css – This is going to be our stylesheet for styling the form.
  • main.js – This contain the script of the project.
  • jQuery Files – The one is the main jQuery file and the other is for validation.

<?php

/* Define MySQL connection details and database table name */
$SETTINGS["mysql_user"]='root';
$SETTINGS["mysql_pass"]='';
$SETTINGS["hostname"]='localhost';
$SETTINGS["mysql_database"]='laraveltuts';
$SETTINGS["USERS"] = 'users'; // this is the default table name that we used

/* Connect to MySQL */
$mysqli = new mysqli($SETTINGS["hostname"], $SETTINGS["mysql_user"], $SETTINGS["mysql_pass"],$SETTINGS["mysql_database"]);
/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}
